Documented bugfix in the NDB-6.2.17 and NDB-6.3.21 changelogs as follows: A race condition in transaction coordinator takeovers (part of node failure handling) could lead to operations (locks) not being taken over and subsequently getting stale. This could lead to subsequent failures of node restarts, and to applications getting into an endless lock conflict with operations that would not complete until the node was restarted. (Fix appears in 6.3.21 rather than 6.3.20 per email from Jörg.)
